Arshad Nadeem PP HI (আরশাদ নাদিম) is a Pakistani javelin thrower. He is the reigning Olympic, Asian and Commonwealth Games champion and the current silver medalist in the World Athletics Championship. His 92.97 metres (305.0 ft) throw at the 2024 Summer Olympics is an Olympic and Asian record and also the sixth longest throw in the history of javelin throw, when considering only the best throw from each athlete.

Nadeem was born into a Punjabi Muslim family in Mian Channu, in the Punjab province of Pakistan. The family belongs to the Jat community. He is the third-oldest among eight siblings. Nadeem was an exceptionally versatile athlete from his early school years. Though he dabbled in all the sports on offer in his school — cricket, badminton, football and athletics — his passion was cricket, and he soon found himself playing it at district-level tape-ball tournaments. Upon entering grade seven in school, Nadeem caught the eye of Rasheed Ahmad Saqi during an athletics competition. Saqi had a history of developing sportspeople in the division, and began training Nadeem soon afterwards.

Nadeem started competing in javelin competitions in 2015. In 2016, he received a scholarship from World Athletics, which made him eligible to train at the IAAF High Performance Training Centre in Mauritius.

In February 2016, Nadeem won the bronze medal at the South Asian Games in Guwahati, India, setting a national record and his personal best at 78.33 m. In June 2016, Nadeem won the bronze medal at the 17th Asian Junior Athletics Championship, held in Ho Chi Minh City.

Nadeem made his debut at the Olympics, representing Pakistan at the 2020 Summer Olympics, which were held in Tokyo in 2021. He became the first Pakistani track and field athlete to qualify for the Olympics. His father stated that Nadeem was not provided with a good training ground facility prior to competing at the Olympics. Nadeem trained in his home's courtyard and on the streets, and is believed to have not received any financial assistance from the Government of Pakistan after qualifying for the Tokyo Olympics. Nadeem has openly spoken about the extreme difficulties of non-cricket sportspeople in Pakistan, who are largely ignored and neglected by sports officials.

From March 2022, until the start of the world championships, Nadeem trained in South Africa under the supervision of coach Terseus Liebenberg. The training was arranged by the Athletics Federation of Pakistan (AFP).

In July 2022, Nadeem participated in the World Athletics Championships in Eugene, Oregon, US, as the sole representative from Pakistan. He finished fifth in the final with a throw of 86.16 m.

Nadeem is married and has a daughter and a son. He is a devout Muslim.

Nadeem describes himself as an introvert. His coach, Salman Iqbal Butt, a former national-level discus thrower, remembered him as a very respectful and obedient athlete who bowed his head as he listened to his coach's words. "He is Zen-like. He is quiet. He is focused, and no matter the setback, he does not let it linger. This is one of the most incredible things about Nadeem, and you cannot really teach it either," his coach said.
